MACHINE FOR EXTBAOTING LIQUID FROM CLOTH.

Specification of Letters Patent. Patented March 31, 1908.

Application filed February 28, 1906. Serial No. 303,358.

5 Germany, have invented a Machine for ExtractingLiquid from Cloth, of which the following is a specification. The ob'ect of this invention is a'machine which will extract the maximum quantity of water from cloth intermediate the washing and drying operations.

Among the advantages of this machine, I may state that liquid may be extracted thereby uniforml and continuousl that it may be accomphshe'd without wrlnklin or creasing the cloth; that the varieties of. 0 0th to which it is a licable are almost unlimited, including plush, velvet, skin imitations and face goods, also carbonized goods; that in the case of face goods, the face is left in better condition; that foreign substances and flocks are removed; that a very large percentage,

reaching as high, in some goods, as of,

the liquid, is removed making the subsequent drying operation much more economical; that the operation is simpler, less laborious and accompanied by less danger to the attendants. f

In the accompanying drawings, Figure 1 is a cross section of the machine. Fig. 2 is a longitudinal section of the "same. Fig. 3 is a detail showing a section of the cloth holder r and one form of cover and thezparts by which they are respectively supported. Figs. 4 and 5 are a cross and longitudinal section showing the means by which the len th-of the slot may'be adjusted to suit d'- erent widths of cloth, Figs. 6 and 7 are details of matic representations of the application of my machine m such manner that the ex-' tracted liquid will run back into the vat in which the cloth is soaked. Fig. 10 is ,a fur ther modification in which an endless a ron is provided to run between the cloth an the details showing two different ways of constructing the vacuum chamber inv one of 50 which (Fig. 12) the chamber is made in one part, and mthe other of which (Fig. 11) the top of the chest 71-is made separate from the body and bolted thereto. p

1, 1,. are the end frames of the machine.

2, is the cloth being treated.

of the cloth holder and vacuum chamber I modifications. Figs. 8 and 9 are diagram- Figs. 11 and 12 are ceived from the washing machine in dripping wet condition.

the frame, aslshown, and thence the 0 0th travels around the tension bars 4, 5, over the spreader bar 6, over the water extracting a paratus, hereinafter described, around t e draft-roll 7, around the lap-roll 8 upon which it may be wound, if desired, or from which it otherwise may continue over the folderroll 9 and down through the folder 10 by Whichit is folded preparatory to being taken to the drying machine, which is preferably of the form shown in U. S. Letters Patent No. 754,649 dated March 15, 1904.

The water extracting apparatus consists of an air and water exhaust on one side of the cloth and a cover upon the opposite side of the cloth, and different parts of my invention relatenot only to the combination of the two but-to the novel features of each.

.11 is a vacuuIn chamber of the pro ortions shown upon which is mounted a 0 0th rest 12. A slot 13 extends through the top .of the vacuum chamber and through the cloth rest so as to present a slotted suction mouth 14' to the cloth. 7

15 is a longitudinal slideway intercepting this slotinwhich are slidably mounted the slides 16 and 17 by which the operative length of the slot may be varied by the attendant at will to suit the width of the cloth being treated. The opposite ends of the vacuum chamber 11 are preferably rovided with the removable heads 18 an 19 to give access to the interior.

' here are two ports leading from the vacuum'chamber 11' an air exhaust port anda liquid exhaust ort numbered respectively, 20 and 21-each of which is preferably protected by asuitable perforated screen or gauze, as shown. islo cated above the bottom of the vacuum chamber so as to be above any li uid that may accumulatein the bottom of t e chamber, and the air exhaust is produced by any suitable air exhaust apparatus orpump connected with the exhaust or suction pipe 22. The liquid exhaust-port. is located at the bottom of thevacuum chamber and in order that the liquid may flow by gravity to the liquid exhaust-port, the bottom 23 of the vacuum chamber is preferably given a This roll-3 is mounted u on The air exhaust port 20- "downward inclination toward said liquid exhaust-port 21. p l

The liquid exhaust-port is provided with a sealed hquid discharge; or, in other words,

one which will discharge the water without substantially interfering with the maintenance of the vacuum or partial vacuum within the vacuum chamber. This water discharge in the form shown in the drawings consists of an outlet passage 24 which is intercepted by a valve or cook 25 that treate contains an internal chamber 26 open on one side only of the cock. VVhen this cock is in the position shown in Fig. 2, it receives the liquid from the vacuum chamber 1] Without admitting air thereto and when the cook 25 is turned, it still prevents the admission of air to the chamber 11 while dis charging through the spout or outlet 27.

In the drawings, the port 20 is shown about the middle of the front of the vacuum chamber 11 and opposite it is shown a removable plate 28. The exhaust liquid port is shown at one end of the vacuum chamber at the bottom below the opening protected by the head 18. By this arrangement, the attendants can not only get at the ports conveniently, but can admit sufficient light to the vacuum chamber through the end openings 18 and 19 to properly attend to any operations that are necessary for cleaning or otherwise treating the interior of the chamber.

The cover may be of either of the forms shown in detail in Figs. 3, 6 or 7, but in practice, I prefer the forms shown in Figs. 3 and 6 and of these two, I prefer the form shown in Fig. 3, which I will therefore first describe. The cover consists of a flexible sheet 29 extending across the machine from end to end of the slot 14 and therefore extendin beyond the edges of the cloth being This flexible sheet is of such material that it will adapt itself to the upper surface of the cloth and under the suction in the slot 14 will hug the cloth against the cloth rest 12 and also hug the surface of the cloth rest itself throughout the length of the slot beyond the edges of the cloth so as to prevent the entrance of any air into the Vacuum chamber excepting such as may pass through'the fibers of the cloth which are being hugged between the cover and the cloth rest. For this purpose, the material that I prefer for the flexible cover 29 is enameled cloth or oil cloth or rubber coated cloth, being substantially impervious to air; but I do not wish to limit myself to either of these kinds of cloth or to a cover which is entirely impervious to air since I am aware that ap roximately good results may be obtained 1 following means for causing the cover to travel with the cloth. 30 is a carrier which in the form shown in Fig. 3 consists of a ro tated cylinder upon the periphery of which is mounted a series of the covers referred to y a flexible cover'which' admits air to some extent.

In the form shown, I-have provided the designated as 29, 29 29, 29. Each of these covers is secured to the periphery of the carrier at oneedge of the cover only, as, for instance, at the edge 31 of the cover 29; the body and opposite edge of the cover being free and each cover being wide enough to overlap the cover succeeding it. By this arrangement, before one cover, as 29, has been carried-beyond the slot 14, the next cover, 2921's in position to cover the slot so that there is no intermission between the action of succeeding covers. The atmospheric pressure upon the top of each cover in turn presses the cover upon the cloth-rest and cloth.

The parts are driven as follows: 32 is the prime moving shaft driven by the belt pulley 33. From this shaft the belt 34 drives the shaft 35 from which is driven the sprocket 38 through the gears 36 and 37'. A chain 39 extends from the s rocket 38 around the sprocket 40 on cocif 26, under the chain tightener 41 and around the sprocket 42 fast to the shaft 43 of the draft roll 7. The

sprocket 44 fast on the shaft 43 drives t1 rough the chain 45 the sprocket 46 fast on the shaft of the cover carrier 30. The parts are so proportioned that the draft-roll 7 draws the cloth forward at the same speed that the carrier 30 draws the cover 29 for ward and, therefore, the unison of motion between the cloth and the series of covers 29 is secured which prevents undue strain being exerted upon the cloth. The belt 47 drives the folding mechanism in a well known manner.

By the connections above described, as the cloth is fed forward, the cook 26 will be constantly turned so as to,'at regular intervals, empty itself of the Water drained into it from the vacuum chamber 11 without destroying the vacuum or partial vacuum in said chamber.

In order to provide for inserting the cloth into the machine, I provide the following mechanism for raising the cover carrier-roll 30: The bearings of this roll are mounted in arms 48 which are pivoted concentric with the shaft 43 of the draft-roll 7. Beneath one of these arms is pivoted the hand lever 49 at 50, which lever is provided with a cam projection 51 operating against the under side of the arm 48 so that when this lever 49 is moved by hand forward, it will raise the cover carrier 30 to permit the introduction of the cloth. By the backward movement of the lever 49, the cover carrier is returned to its normal operative position slightly above the cloth so as to permit the covers to rest upon the surface of the cloth. It will be observed that the cover carrying roll 30 is held slightly offset at the back of the cloth holder 12 so that the successive covers 29 are free of the carrier roll 30 when covering the s 0t.

, 5 upon the sprockets 54and 55. Each of the rods52 carries one edge of one of the covers '29 and the journals of the sprockets are mounted in an arm 411% having thesame mode of operation as the arm 48 already de l scribed.

()ne of the sprockets, 54, is driven from the shaft43of thedraft-roll'7, as in the H form of carrier shown in Figs. 1 and 2. i i .Inthe modification shown in Fig: 7, I have substituted for the, covers 29, acover 56 con? 1 5fs1st1ng of an endless apron. wide enough to" -extendthewhole length of the slot 14 and .1 from the slot 14.

as also in the forms shown in Figsi3 an'd 6, "conforms the surface of the e1eur-rest or support 'IZfadjacent to the exas'haust" passage 14 and enables the cover to acres compress in opposition to the upper surface 'of the cloth-rest or support 12 throughout" a substantial area of that surface on both sides of the exhaust passage 14.

The en'dlessfaproncover is, in this case, carried by the cylinders 57 and 58 arranged vertically'above the slot-14. An adjustment 59 is rovidedxto hold this aprQn' 56 taut and it 40 sists 'inthe addition of'the endless apron 65 running between the cloth and the cloth support 12. "This endless'apron will be of comparatively open textile material .so that it does not substantially interfere with the ac tion of the exhaust while at the same time acting to relieve the cloth from friction between the cloth and the surface of the clothrest 12. This endless apron will preferably be driven by suitablemeans at the same surface speed with the cloth.

passedlthrough the machine preferably face ""upwardmfi 1 .1; In Fig. 8, thecloth-rest or support 1 2 is shown asm'ountedlupon the topof a vacuum chamber 11 from which lead the air exhaustport 20 and the liquidexh'aust portf21 which connects withthe body otafvatin which the clothis being immersedand soaked on its 'ig; 9; between theliquld exit 21 from the vaouum charnberi l'l and the vat" 69 :is

placed an intermediate chamber or reservoir" 61 whereintheliquidj is permitted toaccu mulate'before be-ing di'scharged intothe vat" through the passage 62 {a valve 63 being Patent:

The cloth-rest 12 is generally-mar'le in the form of a solid bronze or brass, casting, which isquiteexpensive; 'but it may be made, as shown in Figs. 11 and 12, of strips of sheet metal, brass, aluminium or copper attached to the'top of the vacuum chamber 11.
